We've just had a string of happy earnings missives from AT&T, Verizon and ARM, so it's not really surprising that the dollar-drenched smartphone effect continues to rage over in Canada too. Rogers Communications just reported Q2 operating profits up 4 percent on the same period last year, amounting to over CA$1.2 billion ($1.3 billion). It won 135,000 new wireless subscribers thanks to a "record number of new smartphone customers", who now make up half of all postpaid subscribers, compared to just 35 percent in June 2010. The carrier also revealed that its smartphone customers tend to be twice as profitable as voice-only types, which tells us there's the scope for it to listen even harder to its customers.
